To install metal roofing, you need to prepare the roof deck, add underlayment, install flashing, and secure metal panels with proper fasteners. Metal roofing is popular because it lasts much longer than asphalt shingles and holds up well in storms. According to RubyHome, metal roofing costs between $10 and $17.05 per square foot for standing seam metal panels, which is more than basic asphalt but pays off over time. Metal roofs can last 40 to 80 years, making them a smart long-term choice. Installing metal roofing is different from asphalt work, so follow each step carefully to avoid leaks and damage.

What Do You Need Before Starting?

Check your roof deck first. Remove old shingles, nails, and debris. Make sure the surface is flat and clean.

Next, add an underlayment. This is a water barrier that sits between the roof deck and metal panels. Use a quality underlayment to stop leaks.

How Do You Install the Underlayment and Flashing?

Lay the underlayment across your roof from bottom to top. Overlap each row by 6 inches. Nail or staple it down to hold it in place.

Install flashing around chimneys, vents, and edges. Flashing stops water from entering these weak spots. Seal all flashing joints with roofing sealant. According to industry data, proper flashing is one of the most important parts of any roof installation.

What Is the Metal Panel Installation Process?

Start at the bottom edge of your roof. Place the first metal panel and align it straight. Use fasteners made for metal roofing, not regular nails.

Secure each panel with fasteners spaced according to the panel type. Do not over-tighten fasteners, as this can crack the metal. Use a pneumatic nailer or hand screwdriver. Each panel overlaps the one below it. Continue this pattern upward until you reach the top ridge.

Metal Roofing Type	Cost Per Sq. Ft.	Lifespan
Standing Seam Metal	$10.00 – $17.05	40 – 80 years
Corrugated Metal	$5.50 – $11.50	40 – 80 years
Steel Shingles	$8.00 – $12.65	40 – 80 years

How Do You Finish the Roof?

Install ridge cap panels at the top of your roof. These cover the seam where two sloped sections meet. Seal ridge caps with roofing sealant.

Check all seams and joints. Seal any gaps with metal roofing sealant. According to RubyHome, metal roofing installation costs range from $4 to $40 per square foot depending on the type and complexity. For a 1,700 square foot roof, total costs can run from $6,800 to $68,000. Hire a professional if you are unsure about any step. A bad installation can cause leaks and cost more to fix later.
